Vehicle Information
Yamaha Phazer MTX 500 Snowmobile (2008-2017)
The Yamaha Phazer MTX 500, produced from 2008 to 2017, is a versatile snowmobile known for its distinctive design and reliable performance. It is powered by a 499cc liquid-cooled, four-stroke, parallel-twin engine, the "Genesis 80FI," delivering 80 horsepower through electronic fuel injection. This engine platform remained consistent throughout the 2008-2017 model years. While no major generational overhaul occurred during this period, Yamaha implemented several minor updates and fixes in the early years, particularly addressing issues identified in the initial 2007 release. These included improvements to cooling, skid components, and steering. Various trims were offered, sharing the same engine, such as the MTX (extended track), GT (trail), RTX (rough terrain), and later the X-TX (144-inch track). Two-up versions like the Venture Lite and MP also utilized this engine. Q: How can I ensure this product fits my specific Yamaha Phazer MTX 500?
